Final answer:
Ezana's stele is a monumental inscription by the Aksumite king Ezana that celebrates his victories and Christian faith, evident during his reign in the fourth century.
Step-by-step explanation:
The inscription on Ezana's stele, created by the Aksumite king Ezana, commemorates his fourth-century military victory against the Nubians and expresses gratitude to the Christian God. This notable inscription provided evidence of the Christianization of Aksum during King Ezana's rule. It is not the Rosetta Stone with three languages serving the purpose of translation.
Instead, it served as a declaration of religious faith and conveyed the king's achievements, including his military successes against the Nubians and Beja people, as well as his devotion to the Christian faith. The transformation of the religious culture of the Aksumite Kingdom is evident in such inscriptions, as well as in the king's coinage, which began to feature the Christian cross.
